Mapping of GI at the urban level is a purely physical mapping. Urban GI is approximated by dividing the land use/land cover classes underlying the Copernicus Urban Atlas into green and non-green classes. The Urban Atlas has been produced for the two reference years 2006 and 2012 for around 500 cities and contains 17 urban and 10 rural classes. Most of the rural and some of the urban classes (e.g. urban parks, the least dense residential classes with sealing degrees of lower than 30%) make up urban green spaces, while e.g. dense residential and industrial and commercial areas are elements of non-green spaces.
The map illustrates the changes in the share of urban green spaces between 2006 and 2012 in a way that the blue dots represent core cities in which the share remained rather stable (i.e. changed not more than 0,5 % in a positive or negative direction). Orange and red dots indicate cities that experienced a decline of green spaces of more than 0,5 %, subdivided into slight (0,5 to 2 % points) and strong (larger than 2 % points) decrease, while green dots show cities with an increase of more than 0,5 %.
